to port or not to port..., sub enclosures Options

[danny_t82]

hi peeps,

if you've been reading my posts u might be aware that i'm about to start constructing my boot install, question is should I port my sub box or not? I have a 12" 300w rms infinity reference sub (4ohms) run off a bridged JBL lc-a752 2 channel amp (150w). The sub box is gonna be smaller than the ported one i use at the mo coz i wanna squeeze its new mdf home in the corner behind the wheel arch on the side of the spare wheel with the most room. The sub will be facing upwards and this is the face I intend to set the port too if you guys think i should stick with it.

Lend me your wisdom!.....

1) There are subs designed for ported applications that sound just as good (and louder) ported than they do sealed. Some would even claim that it sounds better ported. Porting is an art, and requires technical spec calculations in order to be properly done. Check your sub's response to sealed and ported enclosures.

2) SQ will depend on your tuning. You will NOT always lose SQ.

3) Generally speaking, your ported setup will be as loud as DOUBLING the wattage going to your setup (given it is done correctly both ways), or an estimated increase of 2-3 dB. This is why most competitors port. A ported box takes up a LOT more space though.

4) GUYS STOP CLAIMING THAT PORTING WILL MAKE YOU LOSE SQ. This is an ignorant statement.

If you have to ask, just seal them. Chances are you won't care about the difference.

Much love,
